A vaccine designed to tackle Simian Immunodeficiency Virus (SIV), the monkey equivalent of HIV, may have successfully cleared the virus from infected animals. This bodes well for the road ahead for a viable HIV vaccine.

A study published in the Science journal Nature showed that of the 16 monkeys that were exposed to the virus who were subsequently injected with the vaccine, nine appeared to have cleared their body of the disease.

In the Vaccine and Gene Therapy Institute at Oregon Health and Science University, US researchers are now hoping to use a similar approach to test for a vaccine equivalent in humans.
The strain of virus called SIVmac239 which the team examined is up to 100 times more deadly than HIV.

US researchers from the Vaccine and Gene Therapy Institute at Oregon Health and Science University are now hoping to use a similar approach to test for a vaccine equivalent in humans.
The team examined a strain of the virus called SIVmac239, which is up to 100 times more deadly than HIV. Research is still ongoing to determine why the vaccine was only successful in nine monkeys. One reason could be because the SIV is extremely pathogenic. Clinical human trials could start within two years if the vaccine is approved and if permission from regulatory bodies is granted.

It was previously thought that both the human and simian immunodeficiency viruses could be managed with antiretroviral therapies, but not eradicated.

Separately this week, researchers from University of Western Ontario in Canada made a big leap by passing the Phase I HIV vaccine clinical trial applied on humans.

NATIONAL HIV TESTING DAY
June 27, 2016. HIV testing is the only way to know for sure if someone has HIV. According to the Centers for Disease Control and Prevention (CDC), one in eight people in the United States infected with HIV don't know it. Gay and bisexual men are more severely affected by HIV than any other group in the United States.
Among all gay and bisexual men, black/African American gay and bisexual men bear a disproportionate burden of HIV. From 2008 to 2010, HIV infections among young black/African American gay and bisexual men increased 20%.
Gay, bisexual, and other men who have sex with men (MSM) a represent approximately 2% of the United States population, yet are the population most severely affected by HIV. In 2010, young gay and bisexual men (aged 13-24 years) accounted for 72% of new HIV infections among all persons aged 13 to 24, and 30% of new infections among all gay and bisexual men. At the end of 2011, an estimated 500,022 (57%) persons living with an HIV diagnosis in the United States were gay and bisexual men, or gay and bisexual men who also inject drugs.
